iri 0 Report post Posted November 15, 2018 Hi) I have a little problem( When I change alpha parameter in BABYLON.ArcRotateCamera("camera1", -Math.PI/2, 1.3, 50, new BABYLON.Vector3(0, 0, 0), scene); to transform coordinate system the car is stayed in old place. https://www.babylonjs-playground.com/#SSZ2IM#6 How I can rotate my car to new coordinate system?

Deltakosh 4315 Report post Posted November 15, 2018 well this is a pretty LONG PG for such a simple question It could be better to simplify it. I have no idea where you change your alpha value for instance Here I changed the value at construction time: https://www.babylonjs-playground.com/#SSZ2IM#7 (and you can see that it worked as the camera rotated around the car:)) Quote Share this post Link to post Share on other sites
